I. Procurement Background and Application Context In 2025, a municipal sanitation department in Zhuzhou City planned to procure a batch of 3-cubic-meter Dongfeng double-cab sewer cleaning trucks to address urban drainage pipe desilting tasks. The vehicles must comply with blue license plate requirements (drivable with Class C driver’s license), operate efficiently in narrow alleys, deliver high-efficiency desilting performance, and remain within a budget of approximately RMB 287,000 (per publicly available tender information). After multiple rounds of evaluation and on-site inspections, the department selected Chengli Special Purpose Vehicle Co., Ltd.’s Dongfeng double-cab blue license plate 3-cubic-meter sewer cleaning truck solution. In this case, the client commented: “Chengli’s configuration is transparent, its optional equipment logic is clear, and its after-sales service commitment is robust—key factors in its selection.” This article provides an in-depth analysis of the winning bid solution across four dimensions: configuration comparison, value assessment of optional equipment, pricing rationale, and FAQs. II. Standard Version vs. Premium Version Configuration Comparison Based on Chengli Special Purpose Vehicle’s product database and MIIT announcement parameters (e.g., model CLW5070GSSD6), aligned with Zhuzhou’s procurement requirements, the following configuration comparison table is compiled: Configuration Item Standard Version (Base Model) Premium Version (Enhanced Model) Notes Chassis Model Dongfeng double-cab (blue license plate) Dongfeng double-cab (blue license plate) Nationwide warranty; original Dongfeng chassis Engine China VI diesel engine, ~95 HP China VI diesel engine, ~115 HP Higher power output in premium version, better suited for hill climbing in mountainous areas Tank Capacity 3 m³ 3 m³ Complies with blue license plate regulations; weight remains within legal limits Desilting System Hydraulic-driven auger conveyor Hydraulic-driven auger + high-pressure flushing Premium version adds high-pressure flushing for more thorough cleaning Control Method Manual valve control Electric control + remote control Premium version offers greater operational convenience and reduces operator physical strain Discharge Outlet Manual ball valve Hydraulic quick-release valve Premium version improves discharge efficiency by 50% Standard Accessories Standard hoses and couplings Extended hoses, high-pressure water gun, warning lights Premium version includes additional accessories for complex working conditions Reference Price (incl. tax, delivered) ~RMB 225,000 ~RMB 278,000 Subject to final contract terms per local procurement practice As shown in the table, the standard version meets routine desilting needs at a competitive price point; the premium version enhances power, adds high-pressure flushing and electric control systems, making it better suited for high-intensity, high-frequency operations—particularly appropriate for southern Chinese cities like Zhuzhou, where frequent rainfall and prone-to-clogging pipelines demand higher performance. III. Value Analysis of Optional Equipment In the Zhuzhou procurement case, the client opted for a flexible “standard version + selected optional equipment” approach—effectively balancing budget control with enhanced practicality. Below is a value analysis of key optional components: High-Pressure Flushing System (Optional, ~RMB 18,000): Designed to remove stubborn sediment adhering to pipe interiors, high-pressure flushing significantly boosts desilting efficiency and reduces manual secondary cleaning. Zhuzhou clients reported: “After installation, daily desilting capacity per vehicle increased from 8 m³ to 12 m³.” Electric Control & Remote Operation System (Optional, ~RMB 12,000): Enables operators to remotely control desilting operations from outside the vehicle—especially beneficial in narrow alleys or hazardous zones—greatly enhancing operational safety.
